Abstract: An inert non-consumable anode (10, 15), for use in electrolytic production of aluminum from the ore, consistuing of a plurality of parallel vertical wires (50) or rods 844) attached via metallic mesh pads (90) to a suspensded support structure [(30, 40); (34, 48)] which is connected to an electrical power source (120). The wires (50) are made of a high-temperature corrosion-resistant alloy (16) and are durably surface-coated with a noble meatl such as platinum (18) typically deposited by the SCX sputter coating process. During electrolysis the wires (50) are immersed in the fused fluoride bath (72) of the electrolytic furnace at 900 deg C, but remain structurally intact.  Moreover, the catalytic wire coating (18) dissociates any oxides formed, so that no greenhouse gases are given off. To fit full-scale furnaces the inert anode is expanded via linear (10) or circular (15) modules of the wires (50) or rods (44). Compared to carbon anodes now in use, inert anodes are not consumed, create no greenhouse gases, and lower production costs.

Title: Highly filled polymer compositions
Inventor: YALVAC SELIM
IPC: C08K3/00
Filed: 2003-10-17
Granted: 2012-09-04
Abstract: This invention pertains to highly filled polymer compositions comprising a low molecular weight ethylene and/or alpha olefin homopolymers and copolymers, or blends therefrom, filled with high concentrations of fillers or additives.  Examples of such fillers or additives include fire retardants, talc, ceramic manufacturing agents, color concentrates, crosslinking agents, and blowing agents. Because of the low crystallinity (and therefore high percentage of amorphous phase) and low viscosities of the base polymers, highly processable compositions can be formed containing even if containing relatively high loadings of fillers or additives. Such highly filled compositions are thus ideally suited as concentrates or masterbatch formulations for a variety of different compounding applications.
